In 400 the mighty Roman Empire was almost as large as it had ever been; within three centuries, advances by Germanic peoples in western Europe, Slavs in eastern Europe and Arabs around the eastern and southern shores of the Mediterranean had brought about the loss of most of its territory. Ranging from Britain to Mesopotamia, this book explores the changes that resulted from these movements. It shows the different paths away from the classical past that were taken, and how the relatively unified civilization of the ancient Mediterranean gave place to the very different civilizations that cluster around the sea today. This comprehensive and authoritative second edition has been thoroughly revised and updated line-by-line, and contains several new sections dealing for instance with the new evidence provided by recent finds like the Staffordshire Treasure and the widespread effects of the plague. As well as a completely new bibliographical essay, The Roman Empire Divided now also includes six maps and an expanded selection of illustrations fully integrated in the text.
